Abstract: A method and apparatus for reducing power consumption in a mobile terminal having a receiver for receiving a time multiplexed message distributed over a plurality of time slots by receiving a first subset of the plurality of time slots so as to receive a first portion of the time multiplexed message corresponding to the first subset of the plurality of time slots. The mobile terminal then determines from the first portion of the time multiplexed message if additional time slots of the time multiplexed message need to be received by the mobile terminal. The mobile terminal receives a second subset of the plurality of time slots so as to receive a second portion of the time multiplexed message if the mobile terminal determines from the first portion that additional portions of the time multiplexed message are to be received by the mobile terminal. This first portion of the message is preferably independently decodable from the remainder of the message.

Title: Elastic bus interface data buffer
Inventor: SU SAM
IPC: G06F13/38
Filed: 1998-03-10
Granted: 2003-07-15
Abstract: An elastic bus interface receives and registers an external data transfer signal (28) and generates an internal data transfer signal (44) that always begins at the beginning of the subsequent clock cycle regardless of the time of arrival of the external data transfer signal. By employing a plurality of data output registers (54, 56) in a pipeline and using only the internal data transfer signal, data is fed to a bus (25) so as to ensure that almost a complete clock cycle is available for setup time to accomplish data transfer. The invention can operate with high speed buses using only simple conventional circuitry and modest process geometries requiring only minimal chip area and power.

Abstract: An interframe difference signal is generated from the video signal and its one-frame delayed video signal. A filter removes a carrier color signal from the interframe difference signal to output the interframe difference luminance signal. A first motion judging circuit judges a motion in the video signal at a target pixel from the interframe difference luminance signal to output a first motion judging result in accordance with a first edge detection signal. A second motion judging circuit judges a motion in the video signal at the target pixel from a luminance signal and the carrier signal in the interframe difference signal to output a second motion judging result in accordance with a second edge detection circuit. The first and second motion judging results are combined. A majority determining circuit determines majority of the combined result from adjacent Q pixels in accordance with a third edge detection signal. A circular signal generation circuit generates a coefficient K according to the result of the majority determining circuit. The interframe difference signal is multiplied with k to generate a circulation signal. A subtractor subtracts the circulation signal from the video signal to generate an output video signal of which noise is suppressed.

Patent CA-2319302-C (CA)

IPC: B29C55/06
Filed: 2000-09-14
Granted: 2005-11-08
Abstract: A highly stretched film has permanently heat-sealed edges that are nearly invisible. A folding apparatus folds the edge portions of a film to form folded edges. The folded film then is passed through a bridle mechanism having two heated rolls. A series of nips apply pressure to the folded film as it is heated'by the heated rolls. The nip pressure, combined with the heat imparted by the heated rolls, causes thermal welding of the folded edges resulting in permanent heat-sealed edges. Because the film edges are folded prior to the hot-stretching, the hot stretch process performs dual functions of stretching the film and heat sealing the folded edges. The resulting stretched film has permanently heat-sealed edges that do no separate, and which prevent tearing of the film edges during subsequent processing and use.

Abstract: A non-slip, waterproof, water vapor permeable fabric and method of making are described. The fabric is made by obtaining a waterproof, water vapor permeable film and adhering one side of the film to a layer of fabric which may be a stretch fabric. The other side of the film is provided with a discontinuous coating of an elastomer which has an elastic modulus of less than 5.5N/mm2.  The discontinuous coating may take various forms including a pattern of dots or a grid of intersecting lines. The discontinuous coating may optionally project above the surface of the film. The presence of the discontinuous coating of elastomer results in a fabric with a static coefficient of friction of greater than about 1.0 on the discontinuously coated side of the fabric.  The film is preferably a porous expanded polytetrafluoroethylene film provided with a hydrophilic coating on one surface; the hydrophilic coating may serve as an adhesive for joining the one surface of the film to the layer of fabric.  The inventive fabric is useful for various applications such as articles of medical protective clothing including surgical drapes and liners for orthotic braces, which applications may benefit from the non-slip character of the fabric.
